No promoting, en passant or initial 2-square move I assume?
ABBOT CHESS (A NEW PIECE INTRODUCTION)
The Abbot is a new piece that combines the movement of the Bishop and the movement of the Pawn. In other word's Abbot can move only one square forward (if the square is free),...(Abbot can't capture forward) and also can move and capture the same way with the Bishop!
All rules are the same with classical chess, but now there is an important difference on the chessboard.... All of the pieces can change the color of their squares!!!

can it promote? i think its very powerful, maybe 5 points, as it can change colors, but if it cant promote like a pawn i'd be dissappointed
